We need to reinterpret float/double types as uint/ulong in order to
perform the bitwise operations.
This has been tested with piglit, OpenCV, and the ocl conformance tests.
v2:
- Use vector operations rather than splitting vectors into scalar
components.

Vector true is -1, not 1, which means we need to use the relational unary
macro instead of the normal unary builtin one.

relational.h includes relational macros for defining functions which need to
return 1 for scalar true and -1 for vector true.
I believe that this is the only place that this behavior is required, so the
macro is placed at its lowest useful level (same directory as it is used in).
This also creates re-usable unary/binary declaration and floatn includes which
should simplify relational builtin declarations.
Mostly patterned off of include/math/[binary_decl|unary_decl|floatn].inc
but with required changes for relational functions.

The vector components were mistakenly using () instead of {}, which caused
all but the last vector component to be dropped on the floor.
